〔目的〕建立海南省虫媒传染病及其传播媒介的监测平台,以便迅速检测媒介生物,防止外来媒介生物的入侵。〔方法〕选择海口美兰国际机场和三亚凤凰机场附近地带和琼海博鳌-迈汤为重点调查地区,采用挥网和帐诱2种方法,于2009年1月开始调查海南岛蠓科昆虫本底。〔结果〕采获蠓类590余只,经鉴定为4亚科8属,其中包括库蠓(Culicoides)、蠛蠓(Lasiohelea)和细蠓(Leptoconops)三大吸血蠓属。在各采集地中以凤凰机场采获的蠓类最多,占采获蠓类总数的89.51%;在采获的各种蠓类中,以库蠓所占比例最高,为59.05%。在采集蠓类的过程中同时发现在海南岛蠓、蚊和蚋3科吸血双翅目昆虫在旱冬1月的活动种类。在三亚凤凰机场附近调查发现尖喙库蠓(Culicoides oxystoma Kieffer,1910)、异域库蠓(Culicoides peregrinus Kieffer,1910)以及裸蠓属(Atrichopogon)的蠓类在大气相对湿度低于50%的条件下群舞,其成虫雌雄比例达到1:3和1:6。〔结论〕本次调查第1次显示海南岛在旱冬季节不同生境内仍然有多属蠓类活动,首次获得的旱冬季节吸血双翅目昆虫同时活动的生态信息;提供了异域库蠓和尖喙库蠓这2种重要吸血蠓虫的生态信息;获得与热带作物播授花粉有关裸蠓在海南岛旱冬季节仍可进行群舞活动繁育种群的新启示。
[Objective] To establish a surveillance platform for vector-borne infectious disease and its transmission media in Hainan Province in order to detect vector organisms rapidly and prevent the invasion of alien vector organisms. [Methods] Select the Haikou Meilan International Airport and Sanya Phoenix airport near the area and Qionghai Boao - Mai Tang as the key survey areas, using swing net and account lure 2 kinds of methods, in January 2009 began to investigate the Hainan Island Suidaida insect bottom. [Results] More than 590 species of Culicoides were identified and identified as 4 genera and 8 genera, including Culicoides, Lasiohelea and Leptoconops. In the collection sites, the most common types of clams were collected from Fenghuang Airport, accounting for 89.51% of the total number of harvested species. Among the various clams collected, the highest proportion was Ku, accounting for 59.05%. In the process of collecting albacore, we also found the species of sucking blood dipteran insects on the Hainan Island in January, A survey near Fenghuang Airport in Sanya found that Culicoides oxystoma Kieffer (1910), Culicoides peregrinus Kieffer (1910) and Atrichopogon sibiricum were found to be under atmospheric relative humidity below 50% Dance, the adult male and female ratio of 1: 3 and 1: 6. [Conclusion] This survey shows for the first time in this survey that there are still many species of 海-like activity in Hainan Island during the dry season in winter, and the first ecological information of simultaneous activities of the diapause insects in the dry winter season; The beaks of the beak and the beak are the ecological information of the two important blood-sucking pinworms. The new enlightenment is obtained to the breeding population that can still perform the group dancing activities in Hainan Island during the dry season of winter in Hainan Island.
